Testing center of gravity changes between maximum/dry mass

[Dobelong]

Is there any way to easily drain all the fuel from a craft in the editor without checking every individual tank? It would make taking a look at a spaceplane's center of mass when all the fuel is drained, compared to its center of mass with full fuel, much easier.

I use the mod RCS Build Aid for this. It can simultaneously display the wet and dry centers of mass. Without mods, I do not know an easy way to do this in the hanger.

I second RCS Build Aid, very simple and easy to use. There are a couple of other mods that can add/remove fuel across all parts to give a more dynamic idea of what's happening, which can be useful for planes so you don't make it unstable (or too stable i.e. in a nosedive) as you burn fuel, to try and do that by hand with larger craft or those with many fuel tanks/types would be prohibitively complicated.

Nice, I'll need to check that out!
